ok so i recently got over the fear of aproachin women bt now i have another problem, i am horrible at makin conversations, wen i talk it goes good in the begginin, im makin jokes and stuff bt i can only make jokes on a topic for so long u knw, so ill den start askin her what she majors in and stuff like that to get a new subject to make jokes bout bt wen i do this she starts losing interest, a couple of girls called me boring after doin dis and stopped talkin to me, what i want to knw is how do i have a fun and interesting conversation?. also i feel like im too playful at times and not serious at all and some of my friends have told me this also, is that a bad thing?

Two things:

First, this is how it goes. When you get over one sticking point, you are brought to the next one. That's progress. It's like that with public speaking or any social skill (or really any skill).

Second, here is one bit of advice. Try not to rely too much on asking the other person questions. Instead, put forward interesting information yourself. Talk about yourself, tell things you like. Instead of just asking what she does, say "So, I'm doing X, Y, Z. Let me tell you an interesting story about that." THEN once you've done that and given some value, then ask for her story in return.

k thx ill try that
